An additional comment: The reason I asked for the era/manufacture date is the early No. 1 triggers were indeed adjustable. While the later one still had the same "adjustment" screws, but often they made no difference in the pull, no matter how much the screws were turned.
Neither type should interfere with the safety's operation, but you never know....
Did you notice in exchipy schematic shows the sear under saftey, yet mine shows it will not clear to be able to get in that position?
